Featured Reviews

Ivan Kokalovic - PeerSpot reviewer
Facilitates backend service monitoring with efficient log retrieval and API flexibility
Graylog is valuable because it bridges technical knowledge to non-technical teams, presenting complex backend processes in a simple timeline. It boosts the knowledge of sales and customer support teams by allowing them to see the backend operations without needing to read the code. Its API is flexible for visualization, and its powerful search engine efficiently handles large volumes of log data. Moreover, its stability, fast search capabilities, and compatibility with languages like ANSI SQL enhance its utility in IT infrastructure.

Efficient log management enhances activity monitoring despite VPN user issue
Last month, we faced an issue with a Hawaiian VPN user activity. It's like a Fortinet device configured for VPN users. When a VPN user logs in, it doesn't really capture the time before this. If you're testing with existing or new device integration, then the product will be good in the market.
Kyle Vernham - PeerSpot reviewer
Built-in searches and unified data access streamline alert investigation and boosts analyst efficiency
The two features I appreciate the most in Splunk Enterprise Security are the built-in searches, which have been very easy for us to get started with right out of the box, and the fact that it accesses all of our other systems. You can access it as a pane of glass rather than having to search individually. We also have the option to compare our analysts from our service to service. Splunk Enterprise Security helps our SOC team prioritize and investigate high-fidelity alerts more effectively by providing a more in-depth look and the ability to access a lot more of our data. Instead of jumping from several segmented systems, it allows us to have everything brought together in one place. For example, you have to move from our purview to our build system and to Splunk Enterprise Security, and it enables us to streamline that process. The built-in features of Splunk Enterprise Security, which we recently procured, have given us a good starting point and demonstrated the value of the product, providing an easy way to sell it to our company. The ease of getting everything into our purview helps us, and it serves as a good start for the investigation part in one location rather than what we usually have, which is jumping from system to system to system. Splunk Enterprise Security plays a role in our company's strategy to combat insider threats and advanced persistent threats by currently being in its technical test phase. We are still rolling it out, and it should help us find any insider threats based on information that our policy states should not be present in our system. Splunk Enterprise Security's risk-based alerting (RBA) has impacted our alert volume and analyst productivity because we've got many different systems feeding into it. However, it has helped to make it easier for our analysts to go through a set of events rather than 100 alerts. RBA allows us to streamline the process and customize it for our analysts. When it comes to leveraging Splunk Enterprise Security's dashboards and visualizations to communicate security posture to executives, it's pretty straightforward for any type of information. The visualization is easy to understand, but I haven't had any direct conversations with our executives.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Open source and user friendly."
"I am very proud of how very stable the solution is."
"Allowing us to set up alerts and integrate with platforms we already use, such as Slack and OpsGenie to alert users of these errors proactively, is also a very useful feature."
"We're using the Community edition, but I know that it has really good dashboarding and alerts."
"Real-time UDP/GELF logging and full text-based searching."
"The best feature of Graylog is the Elasticsearch integration. We can integrate and we can run filters, such as an event of interest, and those logs we can send to any SIEM tool or as an analytic. Additionally, there are clear and well-documented implementation instructions on their website to follow if needed."
"We have scaled from a single machine installation (a VM with a Graylog + ES + MongoDB) to (2 Graylog + 2 ES + 3 MongoDB). This was done smoothly with a minimal impact on logging."
"The build is stable and requires little maintenance, even compared to some extremely expensive products."
"The dashboard for administrators or assigned engineers can identify vulnerabilities, activities, infected systems, large files, or DDoS attacks."
"It is stable."
"The initial setup is straightforward"
"The log management has helped to improve my organization."
"I have made use of technical support and am certainly very satisfied with them."
"ManageEngine EventLog Analyzer is easy to gather reports to give to management. My supervisor has access to the solution and he enjoys the graphs."
"It's one of the easiest products. It's very simple to use."
"The reporting features are noteworthy, as they provide templates that streamline the process of generating reports"
"It's basically one of the best SIEM products on the market."
"The alerts are very effective."
"The product is generally stable and forgiving."
"It's better than IBM, in my opinion, because it's an independent entity."
"It helped us consolidate all our solutions into an easy tool to use for various employees."
"The most valuable feature of Splunk Enterprise Security is the threat intelligence integration because essentially having to go out and correlate all the data on our own becomes convoluted."
"It is a one stop shop as a full monitoring and alerting solution for operations and application analysis for most of our back-end systems."
"The most valuable feature is the custom dashboard feature."
 

Cons

"I would like to see a default dashboard widget that shows the topology of the clusters defined for the graylog install."
"I hope to see improvements in Graylog for more interactivity, user-friendliness, and creating alerts. The initial setup is complex."
"More customization is always useful."
"When it comes to configuring the processing pipeline, writing the rules can be very tedious, especially since the documentation isn't extensive on how the functions provided for these rules work."
"The biggest problem is the collector application, as we wanted to avoid using Graylog Collector Sidecar due to its architecture."
"There should be some user groups and an auto sign-in feature.​"
"The infrastructure cost is the main issue. I like the rest. If the infrastructure costs could be lower, it would be fantastic."
"I would like to see some kind of visualization included in Graylog."
"There isn't good security integration when it comes to cybersecurity. The correlation of logs isn't so simple."
"The customization of reports could be a lot easier. It is not difficult but it could be made easier."
"Last month, we faced an issue with a Hawaiian VPN user activity."
"The scalability is limited."
"The solution is stable. However, there are limits. For example, we can do 2,500 Syslog events per second, but if we want to do more we have to install the distributor structure, and then we can expand how many events we can do. They could improve the stability."
"It may not be as easy to use as Splunk."
"I would like to see more detailed reports."
"What I'd like to see as an improvement to ManageEngine EventLog Analyzer is for it to be more AI-driven. Having more automation would also make the solution better."
"The price of the solution could be cheaper."
"I find the graphical options really limited and you don't have enough control over how to display the data that you want to see."
"The Web Application Firewall will send you too much information because it's more dedicated to security than a normal firewall."
"Being a SIEM solution with a centralized dashboard, we would like to have more options to customize it."
"Splunk Enterprise Security can be improved mainly from the user interface regarding the visualizations."
"Splunk is not very user-friendly. It has a complex architecture in comparison to other solutions on the market."
"The threat detection library needs to increase the frequency at which the playbooks are updated."
"I've noticed that onboarding data from various multi-cloud sources and diverse products, such as security network devices, can be challenging."
 

Pricing and Cost Advice

"We're using the Community edition."
"Graylog is a free open-source solution. The free version has a capacity limitation of 2 GB daily, if you want to go above this you have to purchase a license."
"Consider Enterprise support if you have atypical needs or setup requirements.​"
"I am using a community edition. I have not looked at the enterprise offering from Graylog."
"We are using the free version of the product. However, the paid version is expensive."
"It's open source and free. They have a paid version, but we never looked into that because we never needed the features of the paid version."
"​You get a lot out-of-the-box with the non-enterprise version, so give it a try first."
"There is an open source version and an enterprise version. I wouldn't recommend the enterprise version, but as an open source solution, it is solid and works really well."
"ManageEngine EventLog Analyzer is expensive. Its licensing costs are annual."
"There is a yearly subscription for the solution."
"Licensing for ManageEngine EventLog Analyzer is paid yearly."
"ManageEngine EventLog Analyzer is a low-cost solution. It costs approximately $1,000 per month per server for a perpetual license."
"We paid for the license of the solution and the deployment. The price of ManageEngine EventLog Analyzer is less expensive than other solutions."
"There is a license required for these solutions. The customer can choose the license type, such as an annual license purchase or a perpetual license. If the customer wants maintenance they will have to pay annually."
"It can be cost-prohibitive when you start to scale and have terabytes of data. Its cost model is based on how much data it processes a day. If they're able to create scaled-down niche or custom package offerings, it may help with the cost. Instead of the full-blown features, if they can narrow the scope where it can only be used for a specific purpose, it would kind of create that market for the product, and it may help with the costing. When you start using it as a central aggregator and you're pumping tons of logs at it, pretty soon, you'll start hitting your cap on what it can process a day. Once you've got that, you're kind of defeating the purpose because you're going to have to scale back."
"In terms of pricing, I believe Splunk is unreasonably costly for the majority of mid and small-sized companies."
"Splunk Enterprise Security's pricing is competitive."
"Splunk ES is quite expensive compared to some products on the market."
"The price of Splunk Enterprise Security is reasonable, falling somewhere in the middle range."
"Splunk Enterprise Security is not at all cost-friendly to be deployed in very small enterprises like start-ups."
"The price of Splunk Enterprise Security is high."
"Splunk Enterprise Security's pricing is pretty competitive."
